Abstract: The present invention relates to a process for the production of a polyethylene by polymerisation of a reaction mixture comprising ethylene in the presence a catalyst system and an antistatic agent according to formula I: (I) wherein R1, R2 and R3 stand for a moiety according to formula II or a hydrocarbon moiety having 1 to 20 carbon atoms (II) wherein each of R4, R5 and R6 may be the same or different, and wherein each of R4, R5 and R6 is a hydrocarbon moiety having 1 to 10 carbon atoms, and wherein at least one of R1, R2 and R3 is a moiety according to formula II. Such process allows for the reduction of sheeting in the polymerisation reactor without compromising the polymerisation reaction kinetics.

Abstract: Process for producing a supported metallocene catalyst system includes: (i) preparing mixture (a) by mixing a metallocene with a cocatalyst; (ii) preparing mixture (b) by reacting an aluminium (II) with an amine (III)t;
wherein each R6 and R10 is hydrogen or a C1-30 hydrocarbon; R7, R8, and R11 are C1-30 hydrocarbon; R9 is hydrogen or a functional moiety comprising at least one active hydrogen; (iii) providing a support material, into a reaction vessel; (iv) providing a solvent into the reaction vessel; (v) supplying mixture (a) and mixture (b) to the reaction vessel; (vi) subjecting the contents of the reaction vessel to a temperature of >60° C. for a period of >3 hrs to obtain a supported catalyst system; and (vii) removing the solvent from the supported catalyst system. Such process allows for the production of a supported metallocene catalyst system having reduced fouling in olefin polymerisation.-

Abstract: Disclosed is a supported nanoparticle catalyst, methods of making the supported nanoparticle 5 catalysts and uses thereof. The supported nanoparticle catalyst includes catalytic metals M1, M2, M3, and a support material. M1 and M2 are different and are each selected from nickel (Ni), cobalt (Co), manganese (Mn), iron (Fe), copper (Cu) or zinc (Zn), wherein M1 and M2 are dispersed in the support material. M3 is a noble metal deposited on the surface of the nanoparticle catalyst and/or dispersed in the support material. The nanoparticle catalyst is 10 capable of producing hydrogen (H2) and carbon monoxide (CO) from methane (CH4) and carbon dioxide (CO2).

Abstract: An ethylene-α-olefin copolymer includes moieties derived from ethylene and moieties derived from an α-olefin comprising 3 to 10 carbon atoms, wherein the copolymer has: a short chain branching ratio (SCBR) of >1.40;
a short chain branching content of ≥15.0/1000 C; a molecular weight distribution Mw/Mn of ≥10.0; and a quantity of polymer moieties derived from an α-olefin comprising 3 to 10 carbon atoms of ≥1.0 and ≤20.0 wt %, with regard to the total weight of the copolymer. Such copolymer demonstrates improved melt processability, as well as allows for manufacturing of films having desirable mechanical properties, in particular in production of films such as by blown film production or by cast film production.
